Non-Universal Stellar Initial Mass Functions: Large Uncertainties in Star Formation Rates at $zapprox 2-4$ and Other Astrophysical Probes

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Joshua J. Ziegler, Thomas D. P. Edwards, Anna M. Suliga, Irene Tamborra, Shunsaku Horiuchi | Summary: We explore the assumption, widely used in many astrophysical calculations, that the stellar initial mass function (IMF) is universal across all galaxies. By considering both a canonical Salpeter-like IMF and a […]

The initial conditions for young massive cluster formation in the Galactic Centre: convergence of large-scale gas flows

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Bethan A. Williams, Daniel L. Walker, Steven N. Longmore, A. T. Barnes, Cara Battersby | Summary: Young massive clusters (YMCs) are compact ($lesssim$1 pc), high-mass (>10${}^4$ M${}_{odot}$) stellar systems of significant scientific interest. Due to their rarity and rapid formation, we have very few examples of […]

Multiple-Photon Resonance Enabled Quantum Interference in Emission Spectroscopy of N_2^+

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Qi Lu, Yalei Zhu, Jing Zhao, Rostyslav Danylo | Summary: Quantum interference occurs frequently in the interaction of laser radiation with materials, leading to a series of fascinating effects such as lasing without inversion, electromagnetically induced transparency, Fano resonance, etc. Such quantum interference effects are […]

Exciton density waves in Coulomb-coupled dual moiré lattices

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Yihang Zeng, Zhengchao Xia, Roei Dery, Kenji Watanabe, Takashi Taniguchi | Summary: Strongly correlated bosons in a lattice are a platform to realize rich bosonic states of matter and quantum phase transitions. While strongly correlated bosons in a lattice have been studied in cold-atom experiments, their realization […]

Brillouin Backaction Thermometry for Modal Temperature Control

Posted by klaurent Caltech

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Yu-Hung Lai, Zhiquan Yuan, Myoung-Gyun Suh, Yu-Kun Lu, Heming Wang | Summary: Stimulated Brillouin scattering provides optical gain for efficient and narrow-linewidth lasers in high-Q microresonator systems. However, the thermal dependence of the Brillouin process, as well as the microresonator, impose strict temperature control requirements for […]

Flexible perceptual encoding by discrete gamma events

Posted by klaurent Yale

Kavli Affiliate: Jessica Cardin | Authors: Quentin Perrenoud, Antonio H. de O. Fonseca, Austin Airhart, James Bonanno, Rong Mao and Jessica A Cardin | Summary: Although behaviorally relevant patterns of neocortical activity in specific frequency bands have been broadly characterized, identifying individual underlying network events remains a key challenge in understanding information processing in cortical […]
